For the thirty-eighth time, the Research and Theory Division of the Association for Educational Communications and Technology (AECT) is sponsoring the publication of these Proceedings. Papers published in this volume were presented at the annual AECT Convention in Indianapolis, Indiana. The Proceedings of AECT's Convention are published in two…

Extraversion and Neuroticism are two fundamental dimensions of human personality that influence cognitive functioning in healthy subjects. Little is known about personality changes that may occur in patients with multiple sclerosis (MS) nor about, in particular, their neurofunctional basis. The aim of this study is to determine the impact of…

Early-onset schizophrenia appears to be clinically more severe than the adult-onset form of the disease. In a previous study, we showed that anatomically related grey and white matter abnormalities found in adolescents patients were larger and more widespread than what had been reported in the literature on adult schizophrenia. Particularly, we…

Objective: The authors describe the epidemiology of infirmary chief complaints aboard a collegiate maritime training ship. Participants: They assessed patients (N = 646 visits) evaluated by the "USTS Enterprise" medical department during a 44-day sea term from January to February 2007. Methods: The authors conducted a retrospective chart review of…

Background: Asthma is one of the most prevalent chronic diseases in the United States and can be life-threatening. There are a rising number of adults with asthma that cannot be prevented or cured but may be controlled. Self-management education is essential for long-term asthma control; however, the most effective type of education is unknown.…

Background: Periodontal disease in Down's syndrome (DS) individuals develops earlier and is more rapid and extensive than in age-matched normal individuals. The present study evaluated a group of DS patients, who had been participating in a 10-year preventive dental programme, for the impact of the programme on their periodontal status. Methods:…

Background: Adults with Down syndrome (DS) are predisposed to syndromic and environmental gastrointestinal conditions. Method: In a hospital-based clinic for adults with DS, a chart audit was conducted to assess the range and frequency of gastrointestinal conditions. Results: From January 2003 to March 2005, 57 patients attended the clinic,…

The present research sought to investigate the role of the basal ganglia in timing of sub- and supra-second intervals via an examination of the ability of people with Parkinson's disease (PD) to make temporal judgments in two ranges, 100-500 ms, and 1-5 s. Eighteen non-demented medicated patients with PD were compared with 14 matched controls on a…

The Functional Transitions Model (FTM) integrates the theoretical notions of progressive functional decline associated with Alzheimer's disease (AD), excess disability, and transitions occurring intermittently along the trajectory of functional decline. Application of the Functional Transitions Model to clinical practice encompasses the paradox of…

Mexican Americans have as much as a six-times greater risk of end-stage renal disease (ESRD) than non-Hispanic white Americans, and women show a faster rate of decline in diabetic renal functioning. The leading treatment for ESRD is hemodialysis, an intensive, complex treatment regimen associated with high levels of patient nonadherence. Previous…

Patient education in asthma management is important; however, there is little known about the characteristics of patients receiving asthma education or how often primary care physicians provide it. The objective of the study was to identify the characteristics of patients receiving asthma education. It was a cross-sectional study using 2001…

The striatum is considered to mediate some forms of procedural learning. Complex dynamic control (CDC) tasks involve an individual having to make a series of sequential decisions to achieve a specific outcome (e.g. learning to operate and control a car), and they involve procedural learning. The aim of this study was to test the hypothesis that…

Despite the increased comprehension of the role of the basal ganglia in cognitive functions such as learning, attention, and executive functions, the exact implication of these structures in language remains unclear. A specific role of basal ganglia in language has been proposed. Nonetheless, a recent hypothesis gives the basal ganglia a…

We aimed to investigate the relation between damage in the corpus callosum and the performance on an interhemispheric communication task in patients with multiple sclerosis (MS). Relative callosal lesion load defined as the ratio between callosal area and the total lesion load in the total corpus callosum, and the diffusion tensor imaging (DTI)…

This research involves an examination of the relationship between education and age on a wide array of neuropsychological test measures among patients diagnosed with Alzheimer's and vascular dementia. The purpose of this study was to investigate the role of education as an attenuating factor to neurocognitive decline in dementia. Although numerous…
